HC04 — Early Invasions, Delhi Sultanate & Provincial Kingdoms

📚 HC04 · Medieval India – I  ·  Chapter 1 of 3 CDS Level ★ High Priority
📌 CDS Focus: Medieval India is consistently one of the highest-yielding sections in CDS History. The Delhi Sultanate dynasties, Alauddin Khilji's reforms, Muhammad bin Tughlaq's experiments, and the Vijayanagara Empire account for 3–5 questions per paper. Memorise dynasty order, key rulers, and their signature policies. Battles of Tarain and Talikota are perennial PYQ favourites.
PART A — EARLY INVASIONS

1. Early Invasions — The Gateway to Medieval India

Three waves of invasion transformed Indian political history before the establishment of the Delhi Sultanate. Each wave had distinct causes, outcomes, and long-term consequences tested in CDS.

1.1 Arab Conquest of Sindh (712 AD) PYQ Repeated

AspectDetail
CommanderMuhammad bin Qasim (sent by Hajjaj bin Yusuf, Governor of Iraq)
DefeatedRaja Dahir of Sindh
BattleBattle of Rawar (712 AD) on the banks of the Indus
SignificanceFirst successful Muslim conquest in India; introduced Arabic administration, Dhimmis status for Hindus/Buddhists
Lasted~100 years; limited to Sindh — did not penetrate further into India
SourceChachnama — the primary account of the conquest

1.2 Mahmud of Ghazni (998–1030 AD) High Priority

Key Fact: Mahmud conducted 17 raids into India (not invasions to stay). His primary motive was plunder, especially of temple wealth. He was also a patron of learning — Alberuni (who wrote Kitab-ul-Hind) and Firdausi (author of Shahnamah) were in his court.
RaidYearTarget / Significance
Somnath1025 ADMost famous raid; plundered the Somnath temple in Gujarat; massive wealth looted
Mathura1018 ADLooted Mathura temples; massacred inhabitants
Nagarkot (Kangra)1009 ADFirst successful hill raid; opened routes into Punjab
Thanesar1014 ADDestroyed Chakraswamin temple
⚠ Common Trap: Mahmud of Ghazni is often confused with Muhammad Ghori. Ghazni = plunder raids, no permanent rule. Ghori = conquest and establishment of Delhi Sultanate. Mahmud is called "Idol-breaker" (But-shikan); Ghori established Turkic rule.

1.3 Muhammad Ghori & Battles of Tarain PYQ Direct

⚔ First Battle of Tarain — 1191 AD

  • Ghori vs Prithviraj Chahamana (Chauhan)
  • Prithviraj won — Ghori was wounded and captured, then released
  • Fought near Tarain (modern Haryana)
  • Prithviraj's magnanimity in releasing Ghori was a strategic blunder

⚔ Second Battle of Tarain — 1192 AD

  • Ghori returned with a stronger army, changed tactics
  • Ghori won decisively; Prithviraj captured and executed
  • Opened the Gangetic plain to Muslim conquest
  • Considered the foundation of Muslim rule in North India
  • Ghori's general Qutb-ud-din Aibak left in charge of India
💡 Mnemonic — Ghori's Other Battles: Tarain 1192 (Prithviraj defeated) → Chandawar 1194 (Jaichand of Kannauj defeated) → Kanauj fell. Remember: T–C–K (Tarain, Chandawar, Kannauj) = Ghori's conquest sequence.
PART B — DELHI SULTANATE (1206–1526)

2. Delhi Sultanate — Five Dynasties

The Delhi Sultanate lasted 320 years across five dynasties. CDS tests the chronological order, key rulers per dynasty, and their landmark contributions. Learn the mnemonic below first.

💡 Mnemonic — Dynasty Order: Slaves Kill Tigers Swiftly & Loudly = Slave → Khilji → Tughlaq → Sayyid → Lodi
DynastyPeriodKey RulersCDS Significance
Slave (Mamluk)1206–1290Aibak, Iltutmish, Razia, BalbanFirst dynasty; foundation of Sultanate
Khilji1290–1320Jalaluddin, Alauddin KhiljiMarket reforms; Mongol repulsion
Tughlaq1320–1414Ghiyasuddin, Muhammad bin, Firoz ShahExperiments; iqta reforms; max territory
Sayyid1414–1451Khizr KhanWeak; claimed descent from Prophet
Lodi1451–1526Bahlul, Sikandar, Ibrahim LodiAfghan dynasty; ended at Panipat 1526

  • Discarded purdah; appeared in public; rode elephants
  • Favoured Abyssinian slave Altunia → nobles revolted

4

  • Established diwan-i-arz (military department)
  • Built strong spy network; ruthless administration

2.2 Khilji Dynasty — Alauddin Khilji Maximum PYQs

Alauddin Khilji (1296–1316) is the most PYQ-tested ruler of the Delhi Sultanate. His market reforms, military conquests, and administrative innovations are asked repeatedly.

Alauddin Khilji's Market Reforms — Structure
4 MARKETS (Mandis) of Alauddin Grain Market (Shahna-i-Mandi) Cloth Market (Sarai Adl) Cattle Market (Horses, cattle) General Market (Misc goods) Controller: Shahna · Intelligence: Barid & Munhiyan · Fixed prices enforced by law Violations = severe punishment (cutting off hands/ears) · Grain stored in Royal Granary
Reform / PolicyDetailsCDS Tip
Market Control4 markets with fixed prices; Shahna (controller), Barid (spies); fines/mutilation for violationAsked as "which official controlled Alauddin's markets?"
Revenue ReformLand revenue raised to 50% of produce; measurement by biswa; removed middlemen (khuts, muqaddams)"Land revenue in Delhi Sultanate was highest under?"
Military ReformsFirst to maintain paid standing army; introduced dagh (branding horses) and chehra (descriptive rolls)"Who introduced dagh system?" — Alauddin
Mongol RepulsionRepelled Mongol invasions 4 times (1297–1308); built defensive forts; resettled Mongols (New Muslims)Malik Kafur = his famous general (South Indian campaigns)
South India CampaignsMalik Kafur led campaigns to Warangal, Dwarsamudra, Madurai; brought enormous wealth"Malik Kafur was the general of?" — Alauddin Khilji

2.3 Tughlaq Dynasty — Muhammad bin Tughlaq Tricky Questions

📌 Token Currency Experiment

  • Introduced brass/copper token currency with same value as silver tanka (~1329–30 AD)
  • Did not prevent people from making coins at home → massive forgery
  • Economy collapsed; scheme abandoned → treasury drained further
  • CDS asks: "Which Sultan introduced token currency?" — Muhammad bin Tughlaq

📌 Capital Transfer to Daulatabad

  • Shifted capital from Delhi to Daulatabad (Devagiri) in Deccan (~1327 AD)
  • Reason: Better central location; protect from Mongol raids
  • Forced the entire population of Delhi to march ~1,100 km
  • Many died en route; scheme reversed after 2 years
  • CDS asks: "Daulatabad was the capital of which Sultan?"
⚠ Muhammad bin Tughlaq's Other Experiments (PYQ): (1) Khorasan Expedition — planned but abandoned; (2) Qarachil Expedition in Himalayas — disaster; (3) Agricultural reforms — Diwan-i-Kohi (Department of Agriculture) created; (4) His reign saw Ibn Battuta's visit (Rihla).

2.4 Firoz Shah Tughlaq PYQ

Key Contributions: Constructed canals (first major irrigation network in medieval India); built cities (Firozabad, Fatehabad, Jaunpur, Hissar); established hospitals (Dar-ul-Shifa); translated Sanskrit texts into Persian; banned torture; abolished ~24 types of taxes. However, he restored Jizyah on Hindus and was lenient on nobles.

2.5 Iqta System Concept PYQ

What is Iqta? An iqta was a territorial assignment (not ownership) granted to a military commander (iqtadar/muqti) in lieu of cash salary. The iqtadar collected revenue from the assigned territory, kept his salary, and sent the surplus to the central treasury. Iltutmish formally organised the system. It was not hereditary — reassigned upon death or misconduct. Often compared to European feudalism (but differs: not hereditary, state-controlled).
